Fâ€™vo, quite apart from the points already raised that, I feel, amply demonstrate the flaws in your idea,
I donâ€™t think that any society can survive if the values it holds are undermined from within. Especially if the undermining process takes the form of an official state policy.

The belief that we are better than murders. Demonstrably so, because we donâ€™t go around chopping bits of people without regard for their wishes simply because we disapprove of their thoughts/actions/looks/what have you,
Is one of those beliefs we take for granted. I know I do.
Now were we to start harvesting kidneys and such from lifers we would be eroding the basis of that belief.
Not only by descending to around their level.
But, and this is possibly even more corrosive to our sense of wellbeing, by denying them a chance, to donate their organs as an act of recompense, by the refusal of which they do so much to secure us in our sense of superiority.
